To all whom t may concern:

Be it known that I, RUSSELL B. KINGMAN, acitizen of the United States, residing at Nest Orange, in the county of Essex and,

State of New Jersey, have invented certain new and useful Improvements in Abrasive Pot-Cloth Fabrics; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in abrasive fabrics; and the invention has reference, more particularly to .a composite vegetable yarn and metallic fabric suitable for use in the manufacture of pot-cloths; scouring-mits and similar articles.

To provide a fabric suitable for use as an abrasive pot-cloth or scouring cloth, it is highly desirable that the body of the cloth. be absorbent so that it will readily take up and hold water or other cleansing fluid, andl it is also highly desirable that the abrasive elements ofthe cloth shall be exposed at the working surface or face of the cloth to the greatest extent or degree possible, so that a maximum amount of the abrading element may be easily brought into eecti've scraping or abrading contact with the surfacev to be cleaned when applyin the cloth thereto. Heretofore it has been t e practice to'produce an abrasive fabric for pot-cleaners by winding or gimping cotton yarn, jute or other vegetable fiber strands with a metallic wire such as copper, and then either weaving or knitting such metal gimped yarns into an open mesh fabric. Abrasivexfabrics so constructed provide but a minimum amount of vegetable yarn, and consequently possess but a limited capacity for absorbing and holding water or other cleansing fluid; and, furthermore, the gimpingI or winding of the metallic wire about the yarn requires a considerable quantity of such metallic wire to be used, less than half of which is effective at the outer face of the fabric for an abradquantity and in relation to the `fabric as a whole, is arranged to provide for a maximum absorption and retention of water or other cleaning fluid, and in which the\ disposition and arrangement of the metallic element of thefabric is such that al maximum amount of the same is exposedso as to project'from the working surface or face of the fabric. To such ends my present inven-` tion comprises, a knitted fabric'composed of one or more vegetable yarn threads and a i metallic thread, the latter consisting, preferably, of a flat .ribbon-like copper wire or strand, the same being interknit toprovide a` ribbed vfabric, with the vegetable yarn predominating in exposure at the rear face or back of the same, and the metallic element forming rib-like portions exposed at and projecting from the front or working face 'of the same.

The inventionv is clearly illustrated in the accompanying drawings, `in which Figure 1 is a plan View of the front or `working face of thenovel abrasive fabric `made according to and embodying the principles of this invention: Figure 2 is a plan view of the rear face or back of the novel fabric; Figure 3 is a plan view of the front or working face of the fabric,` drawn on a the fabric. looking toward the front or working face thereof, and illustrating the manner of interlooping` or knitting the vegetable yarn and metallic strands together to form the fabric; and Figure 6 is a similar view looking toward the rear face or back of the fabric.,

Figure 7 is a perspective view, showing the knitted relation of the vegetable yarn threads when employing double yarn; and Figure 8 is'a plan View, showingthe knitted relation of the vegetable yarn threads when employing a single yarn.

Similar characters of reference are employed in allof the hereinabove described views to indicate corres onding parts.

Referring now to sai drawings, the novel fabric consists of a vegetable yarn Y, preferably in the form of a double yarn thread as shown in Figures 1 to 7 inclusive, or if desired, in the form of a single yarn thread as shown in Figure 8, .with which is knit a metallic thread i M. The vegetable yarn Y ma be made of cotton, jute, or other vegetab e ber, while the metallic thread is pref- `metallic thread M/is likewise knitted to provide rows of loops; alternate loops A12 of each row are interknit or interlocked with corresponding loops 12 of the succeeding rowythus leaving 1n each row free'loops 13 intermediate the interlocked loops 12. In knitting together the yarn thread Y and metallic thread M, the interlocked loops 12 of the latter are carried over and interlocked with the free loops 11 of the former, while at the same time the interlocked loops 10 of the yarn thread are carried beneath and interlocked with the free loops 13 of the metallic thread. Inl this manner a knitted fabric of the rib type is produced in which the metallic thread M is massed in the form of projecting ribs at the front or working face of the fabric, thus exposing a maximum quantity of metal in extension from the workin@ face of the fabric, while the yarn thread Yis massed at the rear face or back of the fabric, thus providing a Huid absorptive element to hold a cleaning fluid which, when the cloth is used will be exuded from'the face of the fabric to soften dirt, grease or the like while the metallic element is producing the desired abrasive or scouring effects. A maximum abrasive effect is obtainedif the metallic element of the fabric is in the form of fiat ribbon-like wire, since such form of wire or thread, when looped and interknit into the body of the fabric, produces wherever exposed at the working face, of the latter, a plurality of chisel-like edges lor scraping points which are mosty efficient in form for the purposes iii-view; however, where a milder abrasive action is desirable round metallic wire or thread may be employed.

While I have described above-one manner of interknitting the yarn and metallic threads to produce the novel pot-cloth fabric, I do not necessarily limit myself to such particular method as to its production, but conceive my present invention to embrace memes any suitable method of knitting or weaving,

so long as it produces the desired preponderance of exposed metallic element at the working face of the cloth, and at the same time provides a substantial body of vegetable yarn adapted to attain the desired maximum water absorption and retention characteristics.

Having thus described my invention, I claim:--

1. An abrasive pot-cloth fabric comprisingr interknit vegetable yarn and metallic threads so combined that the former provide a fabric body adapted to readily absorb and retain cleansing fluids while the latter are disposed to y.provide rib-like abrasive elements exposed on and projecting from the working face of said fabric body.

2. An abrasive pot-cloth fabric comprising knitted vegetable yarn thread to form the body of the fabric and metallic threads interknit with said lyarn thread so as to provide a preponderance of metallic material exposed on the working face ofthe fabric body.

3. An abrasive pot-Cloth fabric comprising vegetable yarn material knitted to provide rows of alternate interlocked and free loops, and metallic material also knitted to provide rows of interlocked loops interengaged with said free loops of vegetable yarn whereby the bulk of the metallic material is connected with and disposed upon the outer working'face of the fabric.

4. An abrasive pot-cloth fabriccomprising interknit vegetable yarn and metallic materials so combined as to form a rib-knitted fabric whereby the yarn material produces surface ribs at the rear face of the resultant fabric and the metallic material produces surface ribs at the front or working face of the fabric as and for the purposes described.

5. An abrasive pot-cloth fabric comprising vegetable yarn material knitted to provide rows of alternate interlocked and free loops, andl flat ribbon-like lmetallic strands also knitted to provide rows of interlocked loops interengaged with said free loops of vegetable yarn whereby said metallic loops are exposed to-project from the outer working qface of the resultant fabric. v

In testimony that I claim the invention set forth above I have hereunto set my hand this 25th day of April, 1925.

RUSSELL B. KINGMAN.
